"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-2146 advisory.

    A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote
    user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that
    causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead
    to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code
    execution. (CVE-2026-80186)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
